Added a loader to the server that automatically detects changes in default cmdsets and typeclasses (like when you change them in settings.py),

loops over all objects in the database and updates the places were the old default was set. This will make it more intuitive to overload the default locations (which is the natural thing to do after all). After this update, just make sure to @reload your server once before editing your settings.py; this will store the old settings for you, so they change-detection can work subsequently.
